The toilet bowl is made out of porcelain. Excessive flow of hard water leads to calcium deposit in the toilet bowls. Even though in the short run it may not cause any harm, as time goes by, the calcium deposit can erode the toilet bowl.

Step 1 – Prep Work and Scrubbing

There is no need to drain the toilet bowl to carry out this process. Just make sure to cut the supply of water to the toilet. Use rubber gloves and scrub the area affected with the calcium built up with a wet pumice stone.

Step 2 – Wipe

After the stain comes off, wipe the toilet bowl with a cloth to rid it of any residue left by the pumice stone.

Step 3 – Water supply

Now turn on the water supply to the toilet. Flush the toilet a couple of time to flush away any dirt. Cleaning the toilet bowl at regular intervals will prevent calcium and other stains from settling in the toilet bowl. If you notice a high content of calcium in the water, then use a soft scrub cleaner. Brush the toilet bowl once every week.
